Abstract
1425265 Electroluminescence MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 22 Feb 1973 [22 Feb 1972] 8827/73 Heading C4S An image modifying apparatus comprises an assembly to which an image can be applied and comprising transparent electrode 15, photoconductive element 14, negative resistance element 13 having a positive temperature coefficient of resistance, electroluminescent element 12 and transparent electrode 11, a direct voltage source being connected directly to provide a non-linear relationship between image and electroluminescent intensities. Changes with temperature of a F.T.C. thermistor characteristic are discussed w.r.t. Fig. 3 (not shown). The critical voltage V c (Fig. 2, not shown) may be varied by heating the thermistor layer so that the anti-halation effect may be achieved at different brightness levels, layer 12 brightness decreasing with input light increase above the critical value, and the contrast increasing in dark field areas. The temperature may be controlled by a heater of metallic wire or thin metallic film in layer 13 (Fig. 4, not shown). Thermistor layer 13 may be formed by applying a paste of the powdered thermistor material dispersed in a vehicle and curing the paste. The electrodes may be of tin oxide, the photoconductor of CdS or CdSe, the luminescent material of ZnS or ZnSe.
